ABSTRACT
<p><b>OBJECTIVE</b>To analyze the dynamic changes in hepatitis B virus (HBV) DNA and hepatitis B surface antigen (HBsAg) levels in chronic hepatitis B (CHB) patients following treatment by antiviral nucleotide drugs over a 5-year follow-up period and to assess the clinical significance of quarterly and annual quantitative measurements.</p><p><b>METHODS</b>One-hundred-and-ten patients with CHB were enrolled in the study and administered on-going standard mono-therapy with various antiviral nucleotide drugs. Over a 5-year period, the HBV DNA level was measured by quantitative PCR every three months and the HBsAg levels were measured by chemiluminescence once a year. The dynamic changes in HBV DNA and HBsAg levels were assessed by Chi-squared test and ANOVA.</p><p><b>RESULTS</b>Only 90 of the CHB patients completed the 5-year follow-up and were included in the analysis. The patients who showed HBeAg-positivity at baseline (study start) had higher levels of HBV DNA and HBsAg than the patients showing HBeAg-negativity. In general, the antiviral nucleotide drug therapy induced downward trends in HBsAg and HBV DNA level over time (F = 17.1, 151.53, all P less than 0.05). However, the most robust reduction in HBV DNA occurred during the first year. The HBsAg level followed an opposite trend, with the most robust reductions occurring in the 3rd, 4th and 5th years of treatment.</p><p><b>CONCLUSION</b>Long-term antiviral nucleotide mono-therapies induced decreases in HBV DNA and HBsAg levels in CHB patients, with the former being most reduced in the short-term and the latter in the long-term.</p>
